150 Vmax OX66 maintenance

[MnToyGuy]

I purchased a boat with a 2000 150 Vmax (6J9 VX150TLRY) on it. The motor runs great and I'd like to keep it that way.

I run non-oxy fuel in it, stabil in the gas over the winter and change the lower unit oil in fall. I did just pick some Yamaha ring free I'll run regularly.

What other regular maintenance items should I be doing or checking?

Thanks!

VST filters,clean injector filters,O2 sensor cleaning and TESTING after cleaning.
plug cap testing.
its a solid motor.
lots of stuff under the hood .
look at the sticky and pull the maint chart for 2 stroke EFI.
remember there is an OR.
whichever occurs FIRST.

Rod, thanks so much!! Is there an FSM online for my motor? I know Yamaha tends to be pretty good about taking them down.

[rodbolt17]

don't know what an FSM is.
however there is a sticky at the start of this forum with the scheduled maint chart.

Factory Service manuals are copy righted material, so Look up the manual # at Yamaha and then do a web search to see what you can find or just buy from Yamaha or your local Yamaha dealer
